Abstract: Abstract A convenient and regioselective sulfonylation/cyclization of 1,6-enynes with arylazo sulfones has been developed to access a series of sulfonylated γ-butyrolactams. The present reaction could be efficiently conducted under catalyst- and additive-free conditions, in which… read more here.
